Description
Technical field
The utility model relates to a kind of fume afterheat focus utilization device of stove.
Background technology
Existing stove adopts traditional heat exchanger to carry out UTILIZATION OF VESIDUAL HEAT IN as heat-treatment furnace, perhaps adopts heat-accumulating burner.Tradition preheater maximum can only be with air and gas preheating to 400 degree, and heat utilization ratio is lower, and low-heat value gas fuel uses and is restricted.The New Regenerative burner can be realized high temperature preheating, and preheat temperature can reach 900 degree, but each burner of heat-accumulating burner all has heat storage, and volume is big, and pipeline is many, and installation is restricted, and key is the price height.Only be suitable for large-scale stove.
Summary of the invention
In order to overcome the shortcoming of prior art, the utility model provides a kind of fume afterheat focus utilization device of stove, and its volume is little, and is easy for installation, the utilization rate of waste heat height, and cost is low.
The technical scheme in the invention for solving the technical problem is: an end of sealing and fixing furnace roof smoke discharging pipe on the exhaust opening of stove, the other end of furnace roof smoke discharging pipe is by a left side, right flue gas reversal valve respectively with a centralized left side, the mouth that advances of right heat storage tank communicates, a left side, the exhaust opening of right heat storage tank communicates with chimney by air-introduced machine, a left side, the cold wind mouth of right heat storage tank communicates with air blast by four-way change-over valve, a left side, the hot-air mouth of right heat storage tank is respectively by a left side, right hot-air valve communicates with hot-air trunk line 12, before hot-air trunk line 12 passes through, back hot- air subtube 16,4 respectively with preceding, back row's burner 17,2 communicate, preceding, back row's burner 17,2 be fixed on described stove before, on the rear wall.
The utility model adopts common burner, and the burner price is low, and is easy for installation.Heat transfer technology adopts concentrates regenerative heat-exchange, and common burner both can reach the heat exchange effect of heat-accumulating burner by concentrating heat storage high-efficiency thermal storage and commutation, and air preheating temperature can reach 900 degree.And the burner volume is the same with common burner, and pipeline is few and install unrestricted.Reached energy-efficient purpose,, reduced more than 25% than the investment of heat-accumulating burner stove than traditional furnace energy-saving 30%.Be particularly suitable for the use of middle-size and small-size stove.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is the utility model user mode vertical view;
Fig. 2 is that A among the utility model Fig. 1 is to view.
The specific embodiment
As shown in drawings, an end of sealing and fixing furnace roof smoke discharging pipe 5 on the exhaust opening 3 of stove 15, the other end of furnace roof smoke discharging pipe 5 is by a left side, right flue gas reversal valve 19,20 respectively with a centralized left side, right heat storage tank 6,10 the mouth that advances communicates, a left side, right heat storage tank 6,10 exhaust opening communicates with air-introduced machine 8 and chimney 9 by four-way change-over valve 7, a left side, right heat storage tank 6,10 cold wind mouth communicates with air blast 13 by four-way change-over valve 7, a left side, right heat storage tank 6,10 hot-air mouth is respectively by a left side, right hot- air valve 14,11 communicate with hot-air trunk line 12, before hot-air trunk line 12 passes through, back hot- air subtube 16,4 respectively with preceding, back row's burner 17,2 communicate, preceding, back row's burner 17,2 be fixed on described stove 15 before, on the rear wall.Described forward and backward row's burner 17,2 also communicates with forward and backward gas pipe 18,1 respectively.
High-temperature flue gas about 1000 ℃ arrives left heat storage tank from the exhaust opening 3 of stove 15 by furnace roof smoke discharging pipe 5, carry out heat exchange with the left heat storage in the left heat storage tank 6, left side regenerator temperature is elevated to about 900 ℃, and flue-gas temperature is reduced to below 150 ℃, discharges from chimney 9 by air-introduced machine 8.Meanwhile, air blast 13 is sent into the combustion air of normal temperature in the right heat storage tank 10, the right heat storage of the high temperature of the right heat storage tank 10 of accumulation of heat begins heat release, the temperature of combustion air is elevated to enter more than 800 ℃ and participates in burning in the stove, right regenerator temperature reduces, and prepares the heat-accumulating process that carries out next circulation.After finishing above heat exchange, left and right flue gas reversal valve 19,20, left and right hot- air valve 14,11 and four-way change-over valve 7 commutations realize left heat storage tank 6 heat releases, right heat storage tank 10 accumulation of heats.So circulation gets final product.Described left and right flue gas reversal valve 19,20, left and right hot- air valve 14,11 and four-way change-over valve 7 have PLC to control automatically.
